Hypertech 2012 GMC sierra 1500 Sle

Reviewed By Donnie B (Coats, NC) Reviewed for a 2012 GMC Sierra —4/9/2015 8:11 PM

I will have to say I was a little undecided on what tuner to get and what not to get and I put the Hypertech on my 2012 GMC Sierra 1500 SLE 4x4 6 1/2 inch lift on 35/12.5/20 and I programmed it for premium fuel and I get a lot more hp and I got about 50 more miles out of my tank of gas and the truck all around runs better and faster..

Best of BOTH worlds...

Reviewed By Jon R (Wichita Falls, TX) Reviewed for a 2012 GMC Sierra —3/18/2015 8:54 PM

Our 2012 GMC Sierra 5.3L truck drives totally different now! Much improved drivability & untraceable full-time V8 if our GM dealer ever checks on it. In just under 2 weeks of driving our MPG has gone UP 0.2 already! This is 90% in town driving too! Also, this device does NOT interfere with the smart phone remote start, lock/unlock, vehicle info functions. Leaving the Range plugged in 24/7, will block the monthly OnStar diagnostic report. So just unplug when vehicle sits unused...

Hooked it up to my truck today and installed one of the canned tunes. Will be getting a custom tune in the future. This is a great product sold by a great company!
